Dragon Vein Agate (Dyed/Treated)
Agate (SiO2)
Hardness 6.5-7 (Mohs scale), colors vary greatly due to artificial dyeing (this one is blue/green with black veins), vitreous to waxy luster, microcrystalline quartz structure (cryptocrystalline), conchoidal fracture.

Physical properties
Hardness 6.5-7 (Mohs scale), colors vary greatly due to artificial dyeing (this one is blue/green with black veins), vitreous to waxy luster, microcrystalline quartz structure (cryptocrystalline), conchoidal fracture.
Formation & geological history
Agate forms as nodules in volcanic rocks or ancient lavas, in former cavities produced by volatiles in the original molten mass. However, the 'dragon vein' pattern is typically created artificially by heating the agate, cooling it rapidly (quenching) to create fractures, and then dyeing it so the dye seeps into the fractures to create the dark veins.
Uses & applications
Commonly used in jewelry, beads, cabochons, and decorative items due to its striking patterns and colors.
Geological facts
Natural agate does not have this specific 'dragon vein' pattern with such contrasting bright colors and dark veins; it is overwhelmingly a chemically treated and dyed product made from less colorful natural agate.
Field identification & locations
Identified by the distinct cracked/veined pattern combined with bright, often unnatural colors. The dye can sometimes fade over time if exposed to strong sunlight.
